What’s the point of an alert about weather that you’re already well into experiencing — thunder, water pouring down, loose soil washed along by the water, flooding basements and ground level floors occurring.

B/c people in an office building all day that are too busy to sit around surfing the internet might not know just how serious it’s getting out there.

Does that mean that at 8:30 it will stop, or does that just mean they will issue a new warning? I’ve had enough. Sump pump can’t keep up, water is rising in my basement, and I’m a sad Melly 🙁 .

Skeptical

How flooded does your basement have to be to be flooded? This is only the second time I’ve had foundation water since moving in, and it isn’t bad so far because I have wizzo drains and a good location, but it makes me wonder how many “dozen” people are squeegeeing their hearts out. Friend just bailed on our dinner date because of a call from home about rising water.
